What is the main purpose of the F21 Lane Guidance Before Junction sign?

When should I move into the lane indicated by the F21 sign?

A common mistake is assuming your GPS is always correct, ignoring the F21 sign. Another trap is not anticipating the lane change early enough, leading to incorrect lane choices or unsafe last-minute manoeuvres.
